[0038] [First embodiment]

[0039] Hereinafter, a connector set 1 including a first connector 10 according to a first embodiment of the present invention will be described with reference to the drawings. Figure 1 It is a perspective view of the connector set 1 according to the first embodiment.

[0040] In this specification, directions are defined as follows. Figure 1 As shown, the direction from the second connector 110 toward the first connector 10 is defined as the downward direction. In addition, the opposite direction of the downward direction is defined as the upward direction. Figure 2As shown, in the first connector 10, the direction in which the first signal terminals 151 are arranged is defined as the front direction. The direction opposite to the front direction is defined as the rear direction. The front-back axis is orthogonal to the up-down axis. In addition, the axis orthogonal to the up-down axis and the front-back axis is defined as the left-right axis. However, the up-down axis, the front-back axis, and the left-right axis in this specification are axes defined for ease of explanation and may not be consistent with the up-down axis, the front-back axis, and the left-right axis when the connector group 1 is used. In addition, in each of the drawings, the up and down directions may be replaced, the left and right directions may be replaced, and the front and rear directions may be replaced.

[0041] In this specification, the positional relationship of components is defined as follows. The first through third components constitute the structure of connector assembly 1. In this specification, "a first component is positioned above a second component" refers to the following state: at least a portion of the first component is positioned directly above the second component. Therefore, when viewed downward, the first component and the second component overlap. This definition also applies in directions other than upward.

[0042] In this specification, "a first member disposed above" a second member includes situations where at least a portion of the first member is directly above the second member, as well as situations where the first member is not directly above the second member but is instead located obliquely above the second member. In this case, the first member and the second member do not need to overlap when viewed from a downward direction. Examples of "obliquely above" include the upper left and upper right. This definition also applies to directions other than upward.

[0043] In this specification, unless otherwise specified, the various parts of the first member are defined as follows. The front portion of the first member refers to the front half of the first member. The front end of the first member refers to the end of the first member in the forward direction. The front end of the first member refers to the front end of the first member and its vicinity. This definition also applies to directions other than the forward direction.

[0044] When any two components in this specification are defined as a first component and a second component, the relationship between the two components has the following meaning. In this specification, the first component being supported by the second component includes the case where the first component is immovably mounted (i.e., fixed) to the second component relative to the second component, and the case where the first component is movably mounted to the second component relative to the second component. In addition, the first component being supported by the second component includes both the case where the first component is directly mounted to the second component and the case where the first component is mounted to the second component via a third component.

[0045] In this specification, the phrase "a first member is retained by a second member" includes a case where the first member is immovably mounted (i.e., fixed) to the second member relative to the second member, and does not include a case where the first member is movably mounted to the second member relative to the second member. Furthermore, the phrase "a first member is retained by a second member" includes both a case where the first member is directly mounted to the second member and a case where the first member is mounted to the second member via a third member.

[0046] In this specification, "a first member and a second member are electrically connected" means that there is electrical conduction between the first and second members. Therefore, the first and second members may or may not be in contact. If the first and second members are not in contact, a third conductive member is positioned between the first and second members.

[0047] In this specification, an axis or member extending in the vertical direction is an axis or member that is inclined within a range of ±45° relative to the vertical direction. Similarly, an axis or member extending in the front-to-back direction does not necessarily refer only to an axis or member parallel to the front-to-back direction. An axis or member extending in the front-to-back direction is an axis or member that is inclined within a range of ±45° relative to the front-to-back direction. An axis or member extending in the left-to-right direction is an axis or member that is inclined within a range of ±45° relative to the left-to-right direction.

[0048] The connector set 1 is used, for example, to connect two circuit substrates. Figure 1 As shown, the connector set 1 includes a first connector 10 and a second connector 110. When the first connector 10 is coupled with the second connector 110, the first connector 10 is located below the second connector 110.

[0049] [Structure of the First Connector]

[0050] Next, the structure of the first connector 10 will be described with reference to the drawings. Figure 2 It is a perspective view of the first connector 10 according to the first embodiment. Figure 3 It is a perspective view of the first signal terminals 151 and 15r and the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 of the first connector 10 according to the first embodiment.

[0051] like Figure 2 as well as Figure 3As shown, the first connector 10 includes a resin body member 11, first signal terminals 151 and 15r, and first ground terminals 16b1 to 16b3 and 16f1 to 16f3. The resin body member 11, first signal terminals 151 and 15r, and first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are integrally formed by insert molding. The first signal terminals 151 and 15r and first ground terminals 16b1 to 16b3 and 16f1 to 16f3 correspond to "first external connection terminals."

[0052] like Figure 2 As shown, the resin main body component 11 includes a bottom portion 11a and a frame portion 11b. When viewed in a downward direction, the frame portion 11b has a ring shape. More specifically, when viewed in a downward direction, the frame portion 11b has a rectangular outer edge and a rectangular inner edge. When viewed in a downward direction, the outer edge of the frame portion 11b and the inner edge of the frame portion 11b respectively have a left side and a right side extending along the front-back axis and a front side and a rear side extending along the left-right axis. When viewed in a downward direction, the bottom portion 11a closes the lower surface of the area surrounded by the frame portion 11b. The material of the resin main body component 11 is an insulating material. The material of the resin main body component 11 is, for example, resin.

[0053] High-frequency signals are input and output to the first signal terminals 15l and 15r. The first signal terminals 15l and 15r are supported by the resin main body component 11. More specifically, a portion of the first signal terminal 15l is embedded in the left side of the frame portion 11b. The first signal terminals 15l are arranged in a row along the front-back axis. The resin main body component 11 is present between adjacent first signal terminals 15l. In addition, a portion of the first signal terminal 15r is embedded in the right side of the frame portion 11b. The first signal terminals 15r are arranged in a row along the front-back axis. The resin main body component 11 is present between adjacent first signal terminals 15r. The first signal terminals 15l and 15r are made by bending a rod-shaped metal member. The material of the first signal terminals 15l and 15r is, for example, a copper-based material such as phosphor bronze.

[0054] The structures of the first signal terminals 151 and 15r will be described in detail with reference to the drawings. Note that the first signal terminal 151 has a structure that is bilaterally symmetrical with the first signal terminal 15r, and therefore its description will be omitted. Figure 4 It is a perspective view of the first signal terminal 15 r according to the first embodiment. Figure 5 It is a cross-sectional view of the first signal terminal 15 r and the frame portion 11 b according to the first embodiment.

[0055] like Figure 4 as well as Figure 5As shown, the first signal terminal 15r includes a main body portion MBa and an exposed portion PE. The main body portion MBa includes a first portion P1a, a second portion P2a, a third portion P3a, a first connecting portion PC1a, and a second connecting portion PC2a.

[0056] The first portion P1a has a first left surface SL1a facing leftward, a first right surface SR1a facing rightward, a first rear surface SB1a and a first front surface SF1a arranged in the front-to-back direction, and a first lower surface SD1a facing downward. The first left surface SL1a does not contact the resin body component 11. Therefore, the first left surface SL1a is exposed from the resin body component 11. The first right surface SR1a, the first rear surface SB1a, the first front surface SF1a, and the first lower surface SD1a are in contact with the frame portion 11b. Therefore, the first right surface SR1a, the first rear surface SB1a, the first front surface SF1a, and the first lower surface SD1a are in contact with the resin body component 11. The first portion P1a extends in the up-down direction. In addition, in this embodiment, the length of the first portion P1a in the left-to-right direction is equal.

[0057] The second portion P2a is located above the first portion P1a. The second portion P2a has a second rear surface SB2a and a second front surface SF2a arranged in the front-to-back direction, a first upper surface SU1a facing upward, and a second lower surface SD2a facing downward. The first upper surface SU1a does not contact the resin body component 11. Therefore, the first upper surface SU1a is exposed from the resin body component 11. The second rear surface SB2a, the second front surface SF2a, and the second lower surface SD2a are in contact with the frame portion 11b. Therefore, the second rear surface SB2a, the second front surface SF2a, and the second lower surface SD2a are in contact with the resin body component 11. The second portion P2a extends in the left-right direction. In addition, in this embodiment, the length of the second portion P2a in the up-down direction is uniform.

[0058] The third portion P3a is located below the second portion P2a. The third portion P3a has a second left surface SL2a facing leftward, a second right surface SR2a facing rightward, and a third rear surface SB3a and a third front surface SF3a arranged in the front-to-back direction. The second right surface SR2a does not contact the resin body component 11. Therefore, the second right surface SR2a is exposed from the resin body component 11. The second left surface SL2a, the third rear surface SB3a, the third front surface SF3a, and the second lower surface SD2a are in contact with the frame portion 11b. Therefore, the second left surface SL2a, the third rear surface SB3a, the third front surface SF3a, and the second lower surface SD2a are in contact with the resin body component 11. The third portion P3a extends in the up-down direction. In addition, in this embodiment, the length of the third portion P3a in the left-to-right direction is equal.

[0059] The first connecting portion PC1a physically connects the upper end of the first portion P1a and the left end of the second portion P2a and is curved. The first connecting portion PC1a has a first inner peripheral surface IS1a facing downward and right, a first outer peripheral surface OS1a facing upward and left, and a third rear surface SB3a and a third front surface SF3a arranged in the front-to-back direction. The first inner peripheral surface IS1a is connected to the first right surface SR1a and the second lower surface SD2a. The first outer peripheral surface OS1a is connected to the first left surface SL1a and the first upper surface SU1a. The third rear surface SB3a is connected to the first rear surface SB1a and the second rear surface SB2a. The third front surface SF3a is connected to the first front surface SF1a and the second front surface SF2a. The first outer peripheral surface OS1a does not contact the resin body member 11. Therefore, the first outer peripheral surface OS1a is exposed from the resin body member 11. The first inner peripheral surface IS1a, the third rear surface SB3a, and the third front surface SF3a are in contact with the frame portion 11b. Therefore, the first inner peripheral surface IS1 a , the third rear surface SB3 a , and the third front surface SF3 a are in contact with the resin main body member 11 .

[0060] The second connecting portion PC2a physically connects the right end of the second portion P2a and the upper end of the third portion P3a and is curved. The second connecting portion PC2a has a second inner peripheral surface IS2a facing downward and leftward, a second outer peripheral surface OS2a facing upward and rightward, and a fourth rear surface SB4a and a fourth front surface SF4a arranged in the front-to-back direction. The second inner peripheral surface IS2a is connected to the second lower surface SD2a and the second left surface SL2a. The second outer peripheral surface OS2a is connected to the first upper surface SU1a and the second right surface SR2a. The fourth rear surface SB4a is connected to the second rear surface SB2a and the third rear surface SB3a. The fourth front surface SF4a is connected to the second front surface SF2a and the third front surface SF3a. The second outer peripheral surface OS2a does not contact the resin body member 11. Therefore, the second outer peripheral surface OS2a is exposed from the resin body member 11. The second inner peripheral surface IS2a, the fourth rear surface SB4a, and the fourth front surface SF4a are in contact with the frame portion 11b. Therefore, the second inner peripheral surface IS2 a , the fourth rear surface SB4 a , and the fourth front surface SF4 a are in contact with the resin main body member 11 .

[0061] In this embodiment, if Figure 4As shown, a first chamfered portion R1a and a second chamfered portion R2a are provided in the first connecting portion PC1a. In addition, a third chamfered portion R3a and a fourth chamfered portion R4a are provided in the second connecting portion PC2a. In addition, the second chamfered portion R2a has a structure that is symmetrical with the first chamfered portion R1a in front and back. In addition, the fourth chamfered portion R4a has a structure that is symmetrical with the third chamfered portion R3a in front and back. In this embodiment, the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a and the fourth chamfered portion R4a are not connected to each other. In addition, the chamfered portions have a shape in which planes are connected by chamfering, a shape in which convex curved surfaces are connected by chamfering, or a shape in which concave curved surfaces are connected by chamfering, etc.

[0062] The third rear surface SB3a is connected to the first inner peripheral surface IS1a via the first chamfered portion R1a. More specifically, when viewed in the front-to-back direction, the first chamfered portion R1a is recessed to the left. In addition, when viewed in the left-to-right direction, the first chamfered portion R1a is recessed to the front. Therefore, as shown in FIG. Figure 5 As shown in FIG. 1 , when viewed in the front-rear direction, the first chamfered portion R1a is recessed in the direction from the first inner peripheral surface IS1a toward the first outer peripheral surface OS1a. Figure 4 As shown, the first chamfer R1a does not reach the third front surface SF3a. The provision of the first chamfer R1a reduces the thickness of the rear end of the first connecting portion PC1a. The first chamfer R1a contacts the frame portion 11b. Therefore, the first chamfer R1a contacts the resin body member 11.

[0063] The third front surface SF3a is connected to the first inner peripheral surface IS1a via the second chamfered portion R2a. More specifically, when viewed in the front-back direction, the second chamfered portion R2a is recessed to the left. In addition, when viewed in the left-right direction, the second chamfered portion R2a is recessed to the rear. Therefore, Figure 5 As shown in FIG. 1 , when viewed in the front-rear direction, the second chamfered portion R2a is recessed in the direction from the first inner peripheral surface IS1a toward the first outer peripheral surface OS1a. Figure 4 As shown, the second chamfer R2a does not reach the third rear surface SB3a. By providing the second chamfer R2a, the thickness of the front end of the first connecting portion PC1a is reduced. The second chamfer R2a contacts the frame portion 11b. Therefore, the second chamfer R2a contacts the resin body member 11.

[0064] The fourth rear surface SB4a is connected to the second inner peripheral surface IS2a via the third chamfered portion R3a. More specifically, when viewed in the front-to-back direction, the third chamfered portion R3a is recessed toward the right. In addition, when viewed in the left-to-right direction, the third chamfered portion R3a is recessed toward the front. Therefore, as Figure 5As shown in FIG. 1 , when viewed in the front-rear direction, the third chamfered portion R3a is recessed in the direction from the second inner peripheral surface IS2a toward the second outer peripheral surface OS2a. Figure 4 As shown, the third chamfer R3a does not reach the fourth front surface SF4a. The provision of the third chamfer R3a reduces the thickness of the rear end of the second connecting portion PC2a. The third chamfer R3a contacts the frame portion 11b. Therefore, the third chamfer R3a contacts the resin body member 11.

[0065] The fourth front surface SF4a is connected to the second inner peripheral surface IS2a via the fourth chamfered portion R4a. More specifically, when viewed in the front-back direction, the fourth chamfered portion R4a is recessed to the right. In addition, when viewed in the left-right direction, the fourth chamfered portion R4a is recessed to the rear. Therefore, as Figure 5 As shown in FIG. 1 , when viewed in the front-rear direction, the fourth chamfered portion R4a is recessed in the direction from the second inner peripheral surface IS2a toward the second outer peripheral surface OS2a. Figure 4 As shown, the fourth chamfer R4a does not reach the fourth rear surface SB4a. Providing the fourth chamfer R4a reduces the thickness of the front end of the second connecting portion PC2a. The fourth chamfer R4a contacts the frame portion 11b. Therefore, the fourth chamfer R4a contacts the resin body member 11.

[0066] The exposed portion PE extends from the lower end of the main body portion MBa to the right. More specifically, the exposed portion PE extends from the lower end of the third portion P3a to the right. Figure 5 As shown, it is exposed from the resin main body member 11.

[0067] First grounding terminals 16b1-16b3 and 16f1-16f3 are connected to the ground potential. First grounding terminals 16b1-16b3 and 16f1-16f3 are supported by the resin body member 11. More specifically, a portion of first grounding terminal 16b1 and a portion of first grounding terminal 16f1 are embedded in the left side of frame portion 11b. Thus, first grounding terminals 16b1 and 16f1 are arranged in a row from back to front. A portion of first grounding terminal 16b2 is embedded in the rear side of frame portion 11b. A portion of first grounding terminal 16b3 and a portion of first grounding terminal 16f3 are embedded in the right side of frame portion 11b. Thus, first grounding terminals 16b3 and 16f3 are arranged in a row from back to front. A portion of first grounding terminal 16f2 is embedded in the front side of frame portion 11b. First grounding terminals 16b1-16b3 and 16f1-16f3 are manufactured by bending a plate-shaped metal member. The first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are made of a copper-based material such as phosphor bronze, for example.

[0068] The structures of the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 will be described in detail with reference to the drawings. Since the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 have the same shape, their description will be omitted. Figure 6 It is a perspective view of the first ground terminal 16f3 according to the first embodiment. Figure 7 It is a cross-sectional view of the first ground terminal 16f3 and the frame portion 11b according to the first embodiment.

[0069] like Figure 6 as well as Figure 7 As shown, the first ground terminal 16f3 includes a main body MBb and a support portion PS. The main body MBb includes a first portion P1b, a second portion P2b, a third portion P3b, a first connecting portion PC1b, and a second connecting portion PC2b.

[0070] The first portion P1b has a first left surface SL1b facing leftward, a first right surface SR1b facing rightward, a first rear surface SB1b and a first front surface SF1b arranged in the front-to-rear direction, and a first lower surface SD1b facing downward. The first left surface SL1b does not contact the resin body component 11. Therefore, the first left surface SL1b is exposed from the resin body component 11. The first right surface SR1b, the first rear surface SB1b, the first front surface SF1b, and the first lower surface SD1b are in contact with the frame portion 11b. Therefore, the first right surface SR1b, the first rear surface SB1b, the first front surface SF1b, and the first lower surface SD1b are in contact with the resin body component 11. The first portion P1b extends in the up-down direction. In addition, in this embodiment, the length of the first portion P1b in the left-to-right direction is equal.

[0071] The second portion P2b is located above the first portion P1b. The second portion P2b has a second rear surface SB2b and a second front surface SF2b arranged in the front-to-back direction, a first upper surface SU1b facing upward, and a second lower surface SD2b facing downward. The first upper surface SU1b does not contact the resin body component 11. Therefore, the first upper surface SU1b is exposed from the resin body component 11. The second rear surface SB2b, the second front surface SF2b, and the second lower surface SD2b are in contact with the frame portion 11b. Therefore, the second rear surface SB2b, the second front surface SF2b, and the second lower surface SD2b are in contact with the resin body component 11. The second portion P2b extends in the left-right direction. In addition, in this embodiment, the length of the second portion P2b in the up-down direction is uniform.

[0072] The third portion P3b is located below the second portion P2b. The third portion P3b has a second left surface SL2b facing leftward, a second right surface SR2b facing rightward, and a third rear surface SB3b and a third front surface SF3b arranged in the front-to-back direction. The second right surface SR2b does not contact the resin body component 11. Therefore, the second right surface SR2b is exposed from the resin body component 11. The second left surface SL2b, the third rear surface SB3b, the third front surface SF3b, and the second lower surface SD2b are in contact with the frame portion 11b. Therefore, the second left surface SL2b, the third rear surface SB3b, the third front surface SF3b, and the second lower surface SD2b are in contact with the resin body component 11. The third portion P3b extends in the up-down direction. In addition, in this embodiment, the length of the third portion P3b in the left-to-right direction is equal.

[0073] The first connecting portion PC1b physically connects the upper end of the first portion P1b and the left end of the second portion P2b and is curved. The first connecting portion PC1b has a first inner peripheral surface IS1b facing downward and right, a first outer peripheral surface OS1b facing upward and left, and a third rear surface SB3b and a third front surface SF3b arranged in the front-to-back direction. The first inner peripheral surface IS1b is connected to the first right surface SR1b and the second lower surface SD2b. The first outer peripheral surface OS1b is connected to the first left surface SL1b and the first upper surface SU1b. The third rear surface SB3b is connected to the first rear surface SB1b and the second rear surface SB2b. The third front surface SF3b is connected to the first front surface SF1b and the second front surface SF2b. The first outer peripheral surface OS1b does not contact the resin body member 11. Therefore, the first outer peripheral surface OS1b is exposed from the resin body member 11. The first inner peripheral surface IS1b, the third rear surface SB3b, and the third front surface SF3b are in contact with the frame portion 11b. Therefore, the first inner peripheral surface IS1 b , the third rear surface SB3 b , and the third front surface SF3 b are in contact with the resin main body member 11 .

[0074] The second connecting portion PC2b physically connects the right end of the second portion P2b and the upper end of the third portion P3b and is curved. The second connecting portion PC2b has a second inner peripheral surface IS2b facing downward and leftward, a second outer peripheral surface OS2b facing upward and rightward, and a fourth rear surface SB4b and a fourth front surface SF4b arranged in the front-to-back direction. The second inner peripheral surface IS2b is connected to the second lower surface SD2b and the second left surface SL2b. The second outer peripheral surface OS2b is connected to the first upper surface SU1b and the second right surface SR2b. The fourth rear surface SB4b is connected to the second rear surface SB2b and the third rear surface SB3b. The fourth front surface SF4b is connected to the second front surface SF2b and the third front surface SF3b. ​​The second outer peripheral surface OS2b does not contact the resin body member 11. Therefore, the second outer peripheral surface OS2b is exposed from the resin body member 11. The second inner peripheral surface IS2b, the fourth rear surface SB4b, and the fourth front surface SF4b are in contact with the frame portion 11b. Therefore, the second inner peripheral surface IS2 b , the fourth rear surface SB4 b , and the fourth front surface SF4 b are in contact with the resin main body member 11 .

[0075] In this embodiment, if Figure 4 As shown, the first connecting portion PC1b is provided with a first chamfered portion R1b and a second chamfered portion R2b. Furthermore, the second connecting portion PC2b is provided with a third chamfered portion R3b and a fourth chamfered portion R4b. Furthermore, the second chamfered portion R2b has a front-to-back symmetric structure with the first chamfered portion R1b. Furthermore, the fourth chamfered portion R4b has a front-to-back symmetric structure with the third chamfered portion R3b. In this embodiment, the first chamfered portion R1b, the second chamfered portion R2b, the third chamfered portion R3b, and the fourth chamfered portion R4b are not connected to each other.

[0076] The third rear surface SB3b is connected to the first inner peripheral surface IS1b via the first chamfered portion R1b. More specifically, when viewed in the front-to-back direction, the first chamfered portion R1b is recessed to the left. In addition, when viewed in the left-to-right direction, the first chamfered portion R1b is recessed to the front. Therefore, as shown in FIG. Figure 7 As shown in FIG. 1 , when viewed in the front-rear direction, the first chamfered portion R1b is recessed in the direction from the first inner peripheral surface IS1b toward the first outer peripheral surface OS1b. Figure 6 As shown, the first chamfer R1b does not reach the third front surface SF3b. ​​The first chamfer R1b reduces the thickness of the rear end of the first connecting portion PC1b. The first chamfer R1b contacts the frame portion 11b. Therefore, the first chamfer R1b contacts the resin body member 11.

[0077] The third front surface SF3b is connected to the first inner peripheral surface IS1b via the second chamfered portion R2b. More specifically, when viewed in the front-back direction, the second chamfered portion R2b is recessed to the left. In addition, when viewed in the left-right direction, the second chamfered portion R2b is recessed to the rear. Therefore, as shown in FIG. Figure 7 As shown in FIG. 1 , when viewed in the front-rear direction, the second chamfered portion R2b is recessed in the direction from the first inner peripheral surface IS1b toward the first outer peripheral surface OS1b. Figure 6 As shown, the second chamfer R2b does not reach the third rear surface SB3b. Providing the second chamfer R2b reduces the thickness of the front end of the first connecting portion PC1b. The second chamfer R2b contacts the frame portion 11b. Therefore, the second chamfer R2b contacts the resin body member 11.

[0078] The fourth rear surface SB4b is connected to the second inner peripheral surface IS2b via the third chamfered portion R3b. More specifically, when viewed in the front-to-back direction, the third chamfered portion R3b is recessed toward the right. In addition, when viewed in the left-right direction, the third chamfered portion R3b is recessed toward the front. Therefore, as Figure 7 As shown in FIG. 1 , when viewed in the front-rear direction, the third chamfered portion R3b is recessed in the direction from the second inner peripheral surface IS2b toward the second outer peripheral surface OS2b. Figure 6 As shown, the third chamfer R3b does not reach the fourth front surface SF4b. The provision of the third chamfer R3b reduces the thickness of the rear end of the second connecting portion PC2b. The third chamfer R3b contacts the frame portion 11b. Therefore, the third chamfer R3b contacts the resin body member 11.

[0079] The fourth front surface SF4b is connected to the second inner peripheral surface IS2b via the fourth chamfered portion R4b. More specifically, when viewed in the front-back direction, the fourth chamfered portion R4b is recessed to the right. In addition, when viewed in the left-right direction, the fourth chamfered portion R4b is recessed to the rear. Therefore, as Figure 7 As shown in FIG. 1 , when viewed in the front-rear direction, the fourth chamfered portion R4b is recessed in the direction from the second inner peripheral surface IS2b toward the second outer peripheral surface OS2b. Figure 6 As shown, the fourth chamfer R4b does not reach the fourth rear surface SB4b. The fourth chamfer R4b reduces the thickness of the front end of the second connecting portion PC2b. The fourth chamfer R4b contacts the frame portion 11b. Therefore, the fourth chamfer R4b contacts the resin body member 11.

[0080] The support portion PS extends rightward from the lower end portion of the first portion P1b.

[0081] In the first connector 10 described above, the lower surface of the resin body member 11 is mounted on a first circuit board (not shown) so that the lower surface faces the first circuit board. More specifically, portions of the first signal terminals 15l and 15r and portions of the first ground terminals 16b1, 16b2, 16b3, 16f1, 16f2, and 16f3 are exposed from the lower surface of the resin body member 11. Therefore, solder is applied to these portions. This electrically connects portions of the first signal terminals 15l and 15r and the first ground terminals 16b1-16b3 and 16f1-16f3 to the electrodes of the first circuit board.

[0082] In the first connector 10, the exposed portion PE extends rightward from the lower end of the first portion P1a. Thus, when viewed from the first portion P1a, the exposed portion PE is located opposite the second portion P2a. The exposed portion PE is the portion that is soldered during assembly of the first connector 10. Meanwhile, the first portion P1a is retained by the resin body member 11. This separation of the first portion P1a and the exposed portion PE facilitates securing the first portion P1a to the resin body member 11 and the exposed portion PE to the first circuit board.

[0083] [Configuration of the Second Connector]

[0084] Next, the structure of the second connector 110 will be described with reference to the drawings. Figure 8 It is a perspective view of the second connector 110 according to the first embodiment. Figure 9 It is a perspective view of the second signal terminals 1151 and 115r and the second ground terminals 116b and 116f of the second connector 110 according to the first embodiment.

[0085] like Figure 8 as well as Figure 9 As shown, second connector 110 includes a resin body member 111, contact terminals 114f1, 114fr, 114b1, and 114br, second signal terminals 1151 and 115r, and second ground terminals 116b and 116f. Resin body member 111, contact terminals 114f1, 114fr, 114b1, and 114br, second signal terminals 1151 and 115r, and second ground terminals 116b and 116f are integrally formed by insert molding. Second signal terminals 1151 and 115r and second ground terminals 116b and 116f correspond to "second external connection terminals."

[0086] like Figure 8As shown, the resin body member 111 includes a protrusion 111a, a frame portion 111b, and a connecting portion 111c. When viewed from above, the protrusion 111a extends along the front-back axis. More specifically, the protrusion 111a has a rectangular parallelepiped shape. When viewed from above, the protrusion 111a has two long sides extending along the front-back axis and two short sides extending along the left-right axis.

[0087] When viewed from above, frame portion 111b has a ring shape surrounding protrusion 111a. Frame portion 111b has left and right sides extending along the front-back axis, and front and rear sides extending along the left-right axis. Furthermore, when viewed from below, protrusion 111a is located within the area surrounded by frame portion 111b. Protrusion 111a does not contact frame portion 111b.

[0088] When viewed from above, connecting portion 111c is located between protrusion 111a and frame portion 111b, connecting protrusion 111a and frame portion 111b. Connecting portion 111c connects the upper portion of protrusion 111a to the upper portion of frame portion 111b. Resin body member 111 is made of an insulating material. For example, resin is used as the material.

[0089] Contact terminals 114fl, 114fr, 114bl, and 114br are connected to the ground potential. Contact terminals 114fl, 114fr, 114bl, and 114br are supported by the resin body member 111. More specifically, contact terminal 114fl is supported on the left side of frame portion 111b. Contact terminal 114fr is supported on the right side of frame portion 111b. Contact terminal 114bl is supported on the left side of frame portion 111b. Contact terminal 114br is supported on the right side of frame portion 111b. Contact terminals 114fl, 114fr, 114bl, and 114br are made of a copper-based material, such as phosphor bronze.

[0090] High-frequency signals are input and output to the second signal terminals 115l and 115r. The second signal terminals 115l and 115r are supported by the resin main body member 111. More specifically, a portion of the second signal terminal 115l is embedded in the left side of the frame portion 111b. The second signal terminals 115l are arranged in a row along the front-back axis. A portion of the second signal terminal 115r is embedded in the right side of the frame portion 111b. The second signal terminals 115r are arranged in a row along the front-back axis. The second signal terminals 115l and 115r are made by bending a rod-shaped metal member. The material of the second signal terminals 115l and 115r is, for example, a copper-based material such as phosphor bronze.

[0091] Second ground terminals 116b and 116f are connected to the ground potential. They are supported by the resin main body member 111. Specifically, a portion of second ground terminal 116b is embedded in the rear end of the frame 111b. A portion of second ground terminal 116b is embedded in the front end of the frame 111b. Second ground terminals 116b and 116f are made by bending a rod-shaped metal member. They are made of a copper-based material, such as phosphor bronze.

[0092] In the second connector 110 described above, the upper surface of the resin body member 111 is mounted on a second circuit board (not shown) so that the upper surface faces the second circuit board. More specifically, portions of the contact terminals 114fl, 114fr, 114bl, and 114br, portions of the second signal terminals 115l and 115r, and portions of the second ground terminals 116b and 116f are exposed from the upper surface of the resin body member 111. Therefore, solder is applied to each of these portions. This electrically connects the contact terminals 114fl, 114fr, 114bl, and 114br, the second signal terminals 115l and 115r, and the second ground terminals 116b and 116f to the electrodes of the second circuit board.

[0093] The frame portion 11b of the first connector 10 is inserted into the area surrounded by the frame portion 111b of the second connector 110. At this time, the protrusion 111a of the second connector 110 is inserted into the area surrounded by the frame portion 11b of the first connector 10. As a result, when the first connector 10 and the second connector 110 are coupled, the first ground terminals 16b1-16b3 contact the second ground terminal 116b and the contact terminals 114bl and 114br. When the first connector 10 and the second connector 110 are coupled, the first ground terminals 16f1-16f3 contact the second ground terminal 116f and the contact terminals 114fl and 114fr. When the first connector 10 and the second connector 110 are coupled, the first signal terminals 15l contact the second signal terminals 115l. When the first connector 10 and the second connector 110 are coupled, the first signal terminals 15r contact the second signal terminals 115r.

[0094] [Effect]

[0095] The first connector 10 can suppress stress concentration on a portion of the terminal when mated with a mating connector. This description will be made using the first signal terminal 15r as an example. As a comparative example, a first signal terminal 25r without the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a will be described with reference to the accompanying drawings. Figure 10It is a cross-sectional view showing the appearance of damage to the resin main body component 11 caused by the contact between the first signal terminal 25r and the second signal terminal 115r. The resin main body component 11 exists between adjacent first signal terminals 25r. When the first connector 10 is combined with the second connector 110, the first signal terminal 25r contacts the second signal terminal 115r. As a result, the first signal terminal 25r is subjected to force in the right direction from the second signal terminal 115r. As a result, stress is concentrated on the intersection line of the third rear surface SB3a and the first inner circumferential surface IS1a and the intersection line of the third front surface SF3a and the first inner circumferential surface IS1a, as well as the intersection line of the fourth rear surface SB4a and the first inner circumferential surface IS1a and the intersection line of the fourth front surface SF4a and the first inner circumferential surface IS1a. In this case, the resin main body component 11 may be damaged. As a result, as Figure 10 As shown in FIG. 1 , there is a case where the portion of the resin main body member 11 surrounded by the first signal terminals 25 r tilts rightward together with the first signal terminals 15 r .

[0096] Therefore, in the first connector 10, the third rear surface SB3a is connected to the first inner peripheral surface IS1a via the first chamfer R1a. As a result, the stress concentration area changes from the intersection (line) of the third rear surface SB3a and the first inner peripheral surface IS1a to the first chamfer R1a (surface), which can disperse stress. The third front surface SF3a is connected to the first inner peripheral surface IS1a via the second chamfer R2a. As a result, the stress concentration area changes from the intersection (line) of the third front surface SF3a and the first inner peripheral surface IS1a to the second chamfer R2a (surface), which can disperse stress. The fourth rear surface SB4a is connected to the second inner peripheral surface IS2a via the third chamfer R3a. As a result, the stress concentration area changes from the intersection (line) of the fourth rear surface SB4a and the first inner peripheral surface IS1a to the third chamfer R3a (surface), which can disperse stress. The fourth front surface SF4a is connected to the second inner peripheral surface IS2a via the fourth chamfer R4a. Thus, the stress concentration point is shifted from the intersection line (line) of the fourth front surface SF4a and the first inner peripheral surface IS1a to the fourth chamfered portion R4a (surface), thereby dispersing the stress. Therefore, the first connector 10 can suppress stress concentration on a portion of the terminal when coupled to a mating connector.

[0097] Furthermore, the first connector 10 can reduce the size of the first signal terminal in the left-right direction. More specifically, when viewed in the front-to-back direction, the first chamfered portion R1a and the second chamfered portion R2a are each recessed in the direction from the first inner peripheral surface IS1a toward the first outer peripheral surface OS1a. Furthermore, when viewed in the front-to-back direction, the third chamfered portion R3a and the fourth chamfered portion R4a are each recessed in the direction from the second inner peripheral surface IS2a toward the second outer peripheral surface OS2a. Furthermore, the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a each contact the resin body member 11. This increases the contact area between the first signal terminal 15r and the resin body member 11 in the region overlapping with the first signal terminal 15r when viewed in the top-to-bottom direction. Consequently, the first signal terminal 15r can increase its strength against shear stress acting at the contact point between the first signal terminal 15r and the resin body member 11. Therefore, even if the first signal terminal 15r is reduced in size in the left-right direction, strength against shear stress acting on the contact portion between the first signal terminal 15r and the resin main body member 11 can be ensured. As a result, the first connector 10 can reduce the size of the first signal terminal in the left-right direction.

[0098] Furthermore, the first connector 10 can narrow the spacing between the first signal terminals. More specifically, by providing the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a, the average distance between adjacent first signal terminals 15r in the front-to-back direction is increased, reducing the capacitance generated between adjacent first signal terminals 15r. This increases the resonant frequency between adjacent first signal terminals 15r. Therefore, even when the spacing between the first signal terminals is narrowed, the effect on the high-frequency characteristics of the high-frequency signals input and output to the first signal terminals 15r can be suppressed. Consequently, the first connector 10 can narrow the spacing between the first signal terminals.

[0099] [First Modification]

[0100] Hereinafter, a first signal terminal 15 r according to a first modified example of the present invention will be described with reference to the drawings. Figure 11 1 is a perspective view of a first signal terminal 15r according to a first modification. Note that, regarding the first signal terminal 15r according to the first modification, only the parts that differ from the first signal terminal 15r according to the first embodiment will be described, and the description will be omitted below.

[0101] like Figure 11As shown, the first signal terminal 15r according to the first modification example differs from the first signal terminal 15r according to the first embodiment in that the first chamfered portion R1a is connected to the third chamfered portion R3a, and the second chamfered portion R2a is connected to the fourth chamfered portion R4a.

[0102] More specifically, first chamfered portion R1a and third chamfered portion R3a are connected to form chamfered portion Ra. Chamfered portion Ra includes first chamfered portion R1a and third chamfered portion R3a. Second chamfered portion R2a and fourth chamfered portion R4a are connected to form chamfered portion Rb. Chamfered portion Rb includes second chamfered portion R2a and fourth chamfered portion R4a.

[0103] The second rear surface SB2a is connected to the second lower surface SD2a via the chamfered portion Ra. The second front surface SF2a is connected to the second lower surface SD2a via the chamfered portion Rb.

[0104] The first connector 10 a including the first signal terminals 15 r according to the first modification example described above also achieves the same effects as those of the first connector 10 .

[0105] [Second Modification]

[0106] Hereinafter, a first signal terminal 15 r according to a second modified example of the present invention will be described with reference to the drawings. Figure 12 This is a cross-sectional view of the first chamfered portion R1a, second chamfered portion R2a, third chamfered portion R3a, and fourth chamfered portion R4a according to the second modification, viewed from the left. Regarding the first signal terminal 15r according to the second modification, only the portions that differ from the first signal terminal 15r according to the first embodiment will be described, and these portions will be omitted.

[0107] like Figure 12 As shown, the first signal terminal 15r involved in the second variant example is different from the first signal terminal 15r involved in the first embodiment in that the length of the first chamfered portion R1a and the third chamfered portion R3a in the left-right direction respectively increases as they go backward, and the length of the second chamfered portion R2a and the fourth chamfered portion R4a in the left-right direction respectively increases as they go forward.

[0108] The first connector 10b having the first signal terminal 15r according to the second modified example described above also achieves the same effects as the first connector 10. Furthermore, the first connector 10b can prevent the first signal terminal from falling out of the resin body member. The length of the first chamfered portion R1a in the left-right direction increases as it moves rearward. As a result, when the first signal terminal 15r is subjected to a force in the rear direction, the first connecting portion PC1 hooks onto the resin body member 11. Furthermore, the length of the second chamfered portion R2a in the left-right direction increases as it moves forward. As a result, when the first signal terminal 15r is subjected to a force in the front direction, the first connecting portion PC1 hooks onto the resin body member 11. Furthermore, the length of the third chamfered portion R3a in the left-right direction increases as it moves rearward. As a result, when the first signal terminal 15r is subjected to a force in the rear direction, the second connecting portion PC2 hooks onto the resin body member 11. Furthermore, the length of the fourth chamfered portion R4a in the left-right direction increases as it moves forward. Thus, when the first signal terminal 15r receives a force in the front direction, the second connection portion PC2 is hooked on the resin main body member 11. Therefore, according to the first connector 10b, it is possible to suppress the first signal terminal from falling off from the resin main body member.

[0109] [Third Modification]

[0110] Hereinafter, a first signal terminal 15 r according to a third modified example of the present invention will be described with reference to the drawings. Figure 13 It is a cross-sectional view of the right end of the first connecting portion PC1a and the frame portion 11b according to the third modification example as viewed in the left direction. Figure 14 11b. The left end of the second connection portion PC2a and the frame portion 11b according to the third modification are shown in cross-sectional view.

[0111] The first signal terminal 15r according to the third modification example differs from the first signal terminal 15r according to the first embodiment in that the length of the first inner peripheral surface IS1a in the front-to-back direction is shorter than the length of the first outer peripheral surface OS1a in the front-to-back direction, and the length of the second inner peripheral surface IS2a in the front-to-back direction is shorter than the length of the second peripheral surface OS2a in the front-to-back direction. Figure 13 As shown in FIG. 1 , at the right end of the first connecting portion PC1a, the length of the first inner peripheral surface IS1a in the front-back direction is shorter than the length of the first outer peripheral surface OS1a in the front-back direction. Figure 14 As shown, at the left end of the second coupling portion PC2a, the length of the second inner peripheral surface IS2a with respect to the front-rear direction is shorter than the length of the second outer peripheral surface OS2a with respect to the front-rear direction.

[0112] The first connector 10c including the first signal terminals 15r according to the third modification example also has the same effects as the first connector 10. Furthermore, the first connector 10c can further suppress stress concentration on a portion of the terminal when coupled to a mating connector.

[0113] [Fourth Modification]

[0114] Hereinafter, a first signal terminal 15 r according to a fourth modified example of the present invention will be described with reference to the drawings. Figure 15 It is a cross-sectional view of the right end of the first connecting portion PC1a and the frame portion 11b according to the fourth modification example as viewed in the left direction. Figure 16 The left end of the second connection portion PC2a and the frame portion 11b according to the fourth modification are viewed from the left.

[0115] The first signal terminal 15r according to the fourth modification is different from the first signal terminal 15r according to the first embodiment in that the length of the first inner peripheral surface IS1a in the front-to-back direction is shorter than the length of the first outer peripheral surface OS1a in the front-to-back direction, and the length of the second inner peripheral surface IS2a in the front-to-back direction is shorter than the length of the second outer peripheral surface OS2a in the front-to-back direction. Figure 15 as well as Figure 16 As shown, when viewed in the left-right direction, the right end of the first inner peripheral surface IS1a has an arc shape protruding downward. When viewed in the left-right direction, the right end of the second inner peripheral surface IS2a has an arc shape protruding downward.

[0116] The first connector 10d including the first signal terminals 15r according to the fourth modification example also has the same effects as the first connector 10. Furthermore, the first connector 10d can further suppress stress concentration on a portion of the terminal when coupled to a mating connector.

[0117] [Other embodiments]

[0118] The first connector according to the present invention is not limited to the first connectors 10 and 10a to 10d, and can be modified within the scope of the gist thereof.

[0119] In addition, there only needs to be one or more first signal terminals.

[0120] Furthermore, the first connectors 10 and 10a to 10d do not need to include the first ground terminals 16b1 to 16b3 and 16f1 to 16f3. In addition, when the first connectors 10 and 10a to 10d include a first ground terminal, there only needs to be one or more first ground terminals.

[0121] Alternatively, the resin main body member 11 , the first signal terminals 151 and 15r , and the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 may be formed by press molding.

[0122] Furthermore, the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 may not have the same shape as each other.

[0123] Furthermore, it is sufficient that at least one of the first chamfer R1a, the second chamfer R2a, the third chamfer R3a, and the fourth chamfer R4a is provided on the first connecting portion PC1a or the second connecting portion PC2a. For example, the third chamfer R3a and the fourth chamfer R4a may be omitted from the second connecting portion PC2a, while the first chamfer R1a or the second chamfer R2a may be provided on the first connecting portion PC1a. Alternatively, the first chamfer R1a and the second chamfer R2a may be omitted from the first connecting portion PC1a, while the third chamfer R3a or the fourth chamfer R4a may be provided on the second connecting portion PC2a.

[0124] In addition, the chamfered portion Ra may not include the first chamfered portion R1a and the third chamfered portion R3a. The second rear surface SB2a may be connected to the second lower surface SD2a via the chamfered portion Ra.

[0125] In addition, the chamfered portion Rb may not include the second chamfered portion R2a and the fourth chamfered portion R4a. The second front surface SF2a may be connected to the second lower surface SD2a via the chamfered portion Rb.
